We look at the division of 86086805 by 249 
We're looking to find how many times 249 goes into 86086805.

Let's proceed to step 1:
The number 249 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 249

Let's proceed to step 2:
249 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 249

Advancing to step 3:
249 can be fit into 860 3 times, resulting in a remainder of 113.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 747 from 860 to get 113.
Include the next digit (8) from the dividend after 113, then repeat: 1138 / 249

Moving on to step 4:
249 goes into 1138 4 times with a remainder of 142.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 996 from 1138 and we're left with 142.
Fetch the next digit (6) from the dividend, attach it to 142 and continue: 1426 / 249

Going ahead to step 5:
249 can be fit into 1426 5 times, resulting in a remainder of 181.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
The remainder is 181 after subtracting 1245 from 1426.
Include the next digit (8) from the dividend after 181, then repeat: 1818 / 249

Let's proceed to step 6:
1818 divided by 249 is 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 3457.0
Subtracting 1743 from 1818 leaves us with 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 249

Step 7:
When dividing 750 by 249, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 34573.0
Deduct 747 from 750 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 249

Going ahead to step 8:
249 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 345730.0
Subtract 0 from 35 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
350 divided by 249 is 1 with a remainder of 101.
Use 1 as the next digit of our solution. 
Result so far: 345730.1
Subtracting 249 from 350 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 10:
The number 249 fits into 1010 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 345730.14
If we subtract 996 from 1010, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
When dividing 140 by 249, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 345730.14
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
1400 divided by 249 is 5 with a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 345730.1405
Subtracting 1245 from 1400 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 13:
1550 divided by 249 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 345730.14056
If we take 1494 away from 1550, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 14:
249 goes into 560 2 times with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 345730.140562
Subtract 498 from 560 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 15:
249 goes into 620 2 times with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 345730.1405622
Deduct 498 from 620 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

In conclusion, the division gives 345730.1405622 with a balance of 1.22e-06.
